In addition to the general purposes of Part 1, the provisions of this Part are intended to serve the purposes of a PRD stated in the Pennsylvania MPC (MPC), as amended, 53 P.S. § 10101 et seq.
The provisions of this chapter and the Subdivision and Land Development Ordinance [Chapter 22] shall apply, except where specific provisions of this Part clearly differ from specific provisions of other sections of this chapter or the Township Subdivision and Land Development Ordinance (SALDO) [Chapter 22]. A PRD shall be considered a subdivision under the SALDO; except that when specific procedural provisions for a PRD under the Pennsylvania MPC, 53 P.S. § 10101 et seq., differ from the SALDO provisions, then the State Planning Code provisions shall apply in place of the SALDO provisions.

The maximum density set forth in § 27-905, Subsection 1, may be reduced by the Board of Commissioners where it is the opinion of the Board of Commissioners that the findings of the site analysis (set forth in § 27-906) justify a modification.
3. 
Building Siting, Building Coverage and Net Residential Density. Within the general standards established in § 27-905, Subsections 1 and 2, the suitability of building siting, building coverage and net residential density will be determined subject to the standards set forth for the site design of residential uses and common open space in § 27-907, Subsections 1 and 2, and the determinations of the site analysis as set forth in § 27-906.
1. 
Natural Features Analysis. In order to determine which specific areas of the total PRD site are best suited for higher-density development, which areas are best suited for lower-density development and which areas should be preserved in their natural state as open space areas, a thorough analysis of the natural features of the site is required. The following subject categories must be included in this analysis:
A. 
Hydrology. Analysis of natural drainage patterns and water resources, including an analysis of streams, natural drainage swales, ponds or lakes, wetlands, floodplain areas, permanent high water table areas, and seasonal high water table areas.

Geological. Analysis of characteristics of rock formations underlying the site, including defining aquifers (particularly those locally subject to pollution), shallow bedrock areas and areas in which rock formations are unstable.
C. 
Soils. Analysis of types of soils present in the site area, including delineation of prime agricultural soil areas, aquifer recharge soil areas, unstable soils, soils most susceptible to erosion, and soils suitable for urban development. The analysis of soils shall be based on the County Soil Survey or more-detailed professional study.
D. 
Topography. Analysis of the terrain of the site, including mapping of elevation and delineation of slope areas over 25%, between 15% and 25%, and between 12% and 15%.

2. 
Community Impact Analysis. In order to determine the impacts of the proposed PRD, an analysis of the potential effects of the PRD upon public facilities, utilities, public school systems and roadway systems will be required. A comparison of the projected costs versus the revenues to the Township and the school district produced by the PRD shall be included in the analysis.

C. 
Dwelling unit structures shall be located and sited so as to promote pedestrian and visual access to common open space wherever possible.
D. 
Dwelling unit structures shall be located and arranged so as to promote privacy for residents within the PRD and maintain privacy for residents adjacent to the PRD.
E.

C. 
Whenever possible, common open space shall be designed as a contiguous area interspersed with residential areas with pedestrian and visual access available to all residents of the PRD.
D. 
Significant natural features, such as woodland areas, large trees, natural watercourses and bodies of water, rock outcroppings and scenic views, shall be incorporated into common open space areas whenever possible; provided, however, that no less than 25% of the total common open space area shall be suitable for intensive use as an active recreation area.

Where extensive natural tree cover and vegetation does not exist and cannot be preserved on the PRD site, extensive landscaping shall be planted to enhance the appearance of the PRD, aid in erosion control, provide protection from wind and sun, screen streets and parking areas, and enhance the privacy of dwelling units.
8. 
Streets. The design and construction of streets shall conform to the requirements of the Township Subdivision and Land Development Ordinance [Chapter 22], except the Board of Commissioners may permit a reduction in the permitted cartway and right-of-way width of streets where the applicant proves that such changes are reasonable.

4. 
Public Dedication of Common Open Space. An offer of dedication of common open space made by the developer in the development plan before the establishment of any organization responsible for common open space areas which is accepted by the Township shall constitute a fulfillment of responsibility for providing and maintaining common open space areas. No such dedication shall be deemed to have been accepted by the Township unless the Board of Commissioners takes formal action to accept the dedication.
1. 
A PRD may be developed in stages if the following standards are met:
A. 
The location and approximate time of construction of each stage is clearly marked on the development plan.

All stages shall be completed consistent with the development plan and shall be of such size and location that they constitute economically sound units of development. In no event shall any one stage contain less than 15% of the total dwelling units included in the development plan.
E. 
Density. To encourage flexibility of housing density, design and type in accord with the purposes of this chapter, gross residential density may be varied from stage to stage. A gross residential density in one stage which exceeds the permitted average gross residential density for the entire PRD must be offset by a gross residential density less than the permitted average gross residential density for the entire development in any completed prior stage, or there must be an appropriate reservation of common open space on the remaining land by a grant of easement or covenant in favor of the Township, which specifies the amount and, if necessary, the location of the common open space.

A. 
The provisions of the development plan relating to: (1) the use, bulk and location of buildings and structures; (2) the quantity and location of common open space, except as otherwise provided in this chapter; and (3) the intensity of use or the density of residential units, shall run in favor of the Township and shall be enforceable in law or in equity by the Township, without limitation on any powers of regulation otherwise granted the Township by law.
B. 
All provisions of the development plan shall run in favor of the residents of the PRD but only to the extent expressly provided in the development plan and in accordance with the terms of the development plan, and to that extent said provisions, whether recorded by plat, covenant, easement or otherwise, may be enforced by law or equity by said residents acting individually, jointly or through an organization designated in the development plan to act on their behalf; provided, however, that no provisions of the development plan shall be implied to exist in favor of residents of the PRD except as to those portions of the development plan which have been finally approved and have been recorded.

B. 
No modification, removal or release of the provisions of the development plan by the Township shall be permitted except upon a finding by the Board of Commissioners, following a public hearing thereon pursuant to public notice called and held in accordance with the provisions of this Part, that the same is consistent with the efficient development and preservation of the entire PRD, does not adversely affect either the enjoyment of land abutting upon or across the street from the PRD or the public interest, and is not granted solely to confer a special benefit upon any person.
C. 
Residents of the PRD may, to the extent and in the manner expressly authorized by the provisions of the development plan, modify, remove or release their rights to enforce the provisions of the development plan, but no such action shall affect the right of the Township to enforce the provisions of the development plan in accordance with the provisions of this section.
